Hi RVRookie,
Not sure how much this will help as my wife and I are pretty much rookies ourselves, but...
We've had a Thor ACE 29.2 for a bit over a year now. Our trips have pretty much been limited to weekends although we had one longer trip late last summer. We're very pleased with it and can't wait to get back out there this year. On the long trip we had 5 of us including our two sons (HS and college) and a friend. Both my boys are over 6' and they didn't seem to have any issues with the height. We had one sleeping in the dinette, one on the sofa and one in the overhead bed that you can drop down over the seats when parked. We also had an 8 month old Great Dane puppy. Might be a bit harder to have that full group at this point with the Dane's growth!
We looked at a wide variety of Class Cs up to 31 feet and Class As up to about 34 feet including some of the small diesels. We finally decided that this was the right choice for us and so far we've been quite happy with our choice. My wife has remarked a few times that she's very happy we picked the one we did. We have a Jeep Wrangler setup to tow four down and have taken that with us on several of the trips. I test drove a few of the motor homes and felt the Class As were easier to see out of. All in all, we've been happy - hope you find the right one for yourselves. We are hoping to do the same when I can finally retire!
Tom
